They’re fun games and I enjoy the concept greatly. I find NiGHTS itself pretty cute (in mannerism as well as appearance) even if it’s not the best written character out there.
I also see NiGHTS as someone who came through adversity to get where it is now,NiGHTS was created a slave in the literal world of nightmares, that doesn’t sound like grand time. NiGHTS represents freedom, or more specifically, breaking free, finding your true self and rejecting the mask forced onto you by others.
In case you haven’t caught on, I see NiGHTS (and Reala) as genderless.
